OMN-16859 AC3a + AC3b — automatic, honest OCC receipt generation, on the omnimarket pilot

Closes the structural gap behind the operator question "we have been trying to get automatic receipt generation working for months, what is still holding us back?"

The gap this closes

Three facts, none of which is a bug in any one component:

  1. The minting producers cannot execute. Both OccCompanionEmitter (born path) and node_occ_companion_compute run in the .201 dev-lane effects runtime, which holds no product-repo checkout — the declared cwd is ${OMNI_HOME}/<repo>, a path absent there. OCC's own hosted compliance runner DECLINES for the same reason.
  2. Eligibility demands PASS before merge. validator_occ_merge_eligibility treats every non-PASS status as ineligible, and the companion must merge before the product PR.
  3. The one surface that CAN execute honestly — the product repo's own CI — has never had a write path into the open companion.

So the receipt had to be PASS at a moment when nothing had run the check. Every previous attempt collapsed into a hand-authored receipt (four occurrences on 2026-08-28 alone) or a status: PASS minted behind a gh pr view PR-existence probe. It is not a filename bug and not a policy problem — it is a missing surface. This PR is that surface.

The mechanical fact that makes it work (verified, not assumed)

omnibase_core/.github/workflows/occ-preflight.yml:244-249 pins occ_sha = headRefOid for an OPEN companion — the companion branch tip, not OCC main. A receipt pushed to that branch is therefore visible to the product PR's very next preflight evaluation. There is no merge-ordering deadlock.

What this PR adds

AC3b — the runner. scripts/ci/occ_receipt_runner.py + .github/workflows/occ-receipt-runner.yml.

  • Resolves Evidence-Source: OCC#<n> from the live PR body with a bounded wait (10 × 30s). The autobind race is handled, not assumed away: no stamp after the bound → exit 0 with an explicit note, and the edited event that carries the stamp re-triggers the workflow.
  • Refuses to write when the companion is not OPEN — a merged companion is pinned by mergeCommit, not headRefOid, so a branch push would be evidence nothing reads.
  • Executes the declared check_value verbatim from the contract via bash -o pipefail -c in the product checkout, capturing real stdout and real exit status. probe_command == check_value by construction, which also satisfies the OMN-15459 S2 family-binding rule and keeps the OCC#5534 laundering channel unreachable.
  • Writes append-only: a net-new base receipt where the key has none, otherwise a net-new <check_type>.supersede.<pr>.yaml record. A merged or born receipt is never opened for write. The push step additionally asserts the tree carries no modified/deleted path and aborts if it does, so a future regression that did edit a merged receipt cannot silently ship.
  • Credential: the existing onexbot-occ-writer App (ONEXBOT_OCC_APP_ID / ONEXBOT_OCC_PRIVATE_KEY), scoped repositories: onex_change_control. No new secret, no new bot, no CROSS_REPO_PAT.
  • Then heals the stale preflight in place (gh run rerun --failed).

Deliberately a separate workflow, not a job in ci.yml: every ci.yml job carries needs: occ-preflight, so a post-test job there could never run while preflight is red — it would deadlock on the exact condition it exists to clear. It is continue-on-error: true, carries no required status-check name, and is in no needs: — registered as EXEMPT in ci_summary_gate with that reason. It is an unblocker, not a gate. A red check is reported by the FAIL receipt it writes (which correctly keeps the companion ineligible), never by failing the job.

AC3a — the honest born receipt. The emitter mints the test_passes receipt status: PENDING instead of PASS behind a gh pr view probe. No schema change needed: EnumReceiptStatus.PENDING already means "the probe was allocated but has not yet executed", and ModelDodReceipt Rule 3 already exempts PENDING from the non-empty-probe_stdout requirement (proven against the real model, not assumed). No PASS is ever minted for an unexecuted check.

Gated to RUNNER_COVERED_REPOS = {OmniNode-ai/omnimarket}, and that direction is the safety property. PENDING is non-PASS, so it holds a companion ineligible until something executes the check — correct only where something will. The emitter serves every product repo from one .201 deployment; minting PENDING everywhere while only omnimarket has a runner would trade a dishonest PASS for an org-wide jam on the ~55% of PRs carrying this item. Install the runner first, then add the repo — never the reverse. Both directions are pinned by tests.

TDD red-first, adversarially proven

47 tests. Red proven by mutation, not just by absence — each of these turns the suite red:

Mutation Fails
No runner module at all (the pre-existing state) all 21
Supersede record hardcodes check_type: command — the live OCC#7465 defect 2, incl. the leg driving core's real resolve_supersession
Writer edits the base receipt instead of appending 4
Status always PASS regardless of exit status 1
verifier == runner (silent ADVISORY downgrade) 3
PENDING minted outside RUNNER_COVERED_REPOS 2

Two runner tests execute real subprocesses — a real success and a real failure — so the executor is proven to be an executor and not a formatter.

dod_evidence

  • uv run pytest tests/unit/scripts/test_occ_receipt_runner_omn_16859.py tests/unit/nodes/node_pr_lifecycle_fix_effect/test_born_pending_receipt_omn_16859.py tests/unit/nodes/node_pr_lifecycle_fix_effect/test_born_path_behavior_proof_omn_16892.py -q → 47 passed
  • uv run mypy src/omnimarket/ --strict → Success: no issues found in 3086 source files
  • uv run ruff format --check src/ tests/ + uv run ruff check src/ tests/ → clean
  • pre-commit run --all-files → green, no Failed hooks (incl. the OCC emitter golden gate and Receipt Honesty Gate)
  • Governed impacted-test selector (pre-push, OMN-13973) → passed on this branch

Two CI gates correctly caught this work and were satisfied rather than bypassed: ci_summary_gate's PR-triggered-job classification (the new job is now EXEMPT with a stated reason) and the hardcoded-literal gate (the ABS_PATH prefixes are annotated, since their absence is the assertion).

Honest status on live proof

The runner workflow lands ARMED, not yet proven end to end. A workflow only executes on a PR opened after it is on the base branch, so this PR cannot run its own runner. The next omnimarket product PR is the natural first execution.

The AC3a bridge is additionally inert until the .201 dev-lane effects runtime is redeployed carrying this omnimarket code — the same standing dependency recorded for #2195. Until then omnimarket's born receipts keep the old PASS, and the runner (which does not depend on the redeploy) writes a net-new base receipt rather than a supersession record. Both paths are covered by tests.

Companion piece

Eligibility legibility (AC3c) ships separately in omnibase_core — a PENDING receipt on a runner-covered check type reports a distinct, actionable reason instead of the misleading missing_receipt, while staying eligible=False. This PR does not depend on it.

Ticket: OMN-16859 (AC3a, AC3b). AC1 / AC2 / AC4 landed previously in #2195.

…s and writes them into the open companion

AC3b + AC3a. Closes the structural gap that has blocked automatic OCC
receipt generation: the minting producers run in the .201 effects runtime
with no product-repo checkout, so neither can execute a `test_passes`
check, while eligibility requires a PASS receipt before the companion
merges. The one surface that can execute honestly — product-repo CI —
had no write path into the open companion. This adds it.

- scripts/ci/occ_receipt_runner.py: reads the open companion's contracts,
  selects declared items whose check_type it can honestly execute
  (test_passes), executes the declared check_value verbatim in the product
  checkout, and writes the result append-only — a net-new base receipt
  where none exists, otherwise a net-new <check_type>.supersede.<pr>.yaml
  record. No merged or born receipt is ever edited.
- .github/workflows/occ-receipt-runner.yml: product-PR workflow, separate
  from ci.yml (every ci.yml job has `needs: occ-preflight`, so a job there
  could never run while preflight is red). Bounded wait for the autobind
  race, existing OnexBot-OCC-Writer App credential (no new secret), and a
  preflight heal after the push. continue-on-error, never a required check.
- AC3a bridge: the born test_passes receipt is minted PENDING, not a PASS
  behind a `gh pr view` probe. Gated to RUNNER_COVERED_REPOS so a repo
  without a runner is unchanged byte-for-byte — install the runner first,
  then add the repo.

Sound because occ-preflight pins an OPEN companion to headRefOid, the
branch tip: a receipt pushed there is visible to the next preflight, so
there is no merge-ordering deadlock.

Red-first: 21 runner tests + 11 bridge tests. Adversarially proven by
mutation — editing the base receipt, hardcoding the record's check_type
(the live OCC#7465 defect), always-PASS, and self-attestation each turn
the suite red.

📝 Walkthrough

Walkthrough

This change adds a non-blocking GitHub Actions workflow and a product-repository runner for OCC receipts. It also changes covered born receipts from fabricated PASS to PENDING until product CI executes the declared check.

Changes

OCC receipt flow

Layer / File(s) Summary
Born receipt status handling
src/omnimarket/nodes/node_pr_lifecycle_fix_effect/handlers/occ_evidence_stamp.py, src/omnimarket/nodes/node_pr_lifecycle_fix_effect/handlers/occ_companion_emitter.py, tests/unit/nodes/node_pr_lifecycle_fix_effect/*
Covered test_passes receipts start as PENDING. Other receipts retain PASS. Tests validate status selection, rendering, coverage gates, and emitted receipt content.
Receipt runner execution and persistence
scripts/ci/occ_receipt_runner.py, tests/unit/scripts/test_occ_receipt_runner_omn_16859.py
The runner executes declared checks, captures real results, validates contracts, resolves supersession chains, prevents path leakage, and writes append-only receipts. Tests cover execution, persistence, idempotency, schema validation, and parsing.
Workflow orchestration and publication
.github/workflows/occ-receipt-runner.yml, tests/unit/scripts/ci/test_ci_summary_gate.py
The workflow discovers eligible companion branches, installs dependencies, invokes the runner, rejects non-append-only changes, pushes new receipts, reruns failed OCC jobs, and remains exempt from blocking CI summary enforcement.

Estimated code review effort: 5 (Critical) | ~90+ minutes

Merge Risk: 🟠 High · up to 17c74

The new receipt runner executes commands supplied by an open companion without first validating that the companion came from the trusted automation path, which could expose repository credentials to untrusted shell content. The workflow also has a portability issue that may prevent it from finding the product PR on some configured runners, so this PR is not ready to merge until those risks are addressed.

This test does not reach the guard it describes.

The first _execute writes a supersession record whose replacement status is PASS. On the second _execute, _resolved_status resolves that record to PASS, so the runner takes the skipped_already_pass branch and never reaches the record_path.exists() guard in scripts/ci/occ_receipt_runner.py (Lines 481-491). The assertions pass, but the overwrite guard stays uncovered.

Add a case where the existing record does not resolve to PASS, for example a record written from a failing check, and assert that the runner reports a failure entry instead of rewriting the record.

…e any check_value executes

CodeRabbit review on #2205, both findings valid and fixed here.

1. Provenance (Major). The Evidence-Source stamp is an author-editable pointer
   and 'edited' is one of this workflow's triggers, so the companion it names
   was untrusted input feeding a contract whose check_value the runner executes
   verbatim on a job holding an OCC write token. The stamp is now treated as an
   untrusted pointer: before the companion is cloned, it must independently
   prove it was opened by the OCC-writer App (so its contract is
   emitter-generated, not hand-written) AND that its branch is the autobind
   branch minted for THIS product PR (so the stamp cannot be repointed at an
   unrelated companion). Failing the gate is a clean skip, never a hard failure.

2. Portability (Minor). Dropped the non-portable sed 'I' modifier; the
   expression's character classes already handle case, and '|| true' would have
   masked a BSD sed rejection as an empty companion id.

No OCC evidence companion was minted for this PR.

this PR is already bound to OCC#7587; its evidence companion exists and nothing needs authoring

To clear this: Nothing to do — the companion already exists.

Reported by node_occ_companion_effect (decline code already_bound, OMN-16665). This decision was made against the PR's LIVE state at compute time, not at publish time — a green publisher job only means the command reached the broker.
